3.5 Floor Support and Protection

• The ﬁreplace must be placed directly on a wood or non-

combustible surface (not linoleum or carpet) extending the

entire depth and width of the ﬁreplace

• If this appliance is to be installed directly on carpeting, tile,

or other combustible material other than wood ﬂooring,

this appliance shall be installed on a metal or wood panel

extending the full width and depth of the appliance.

• If the appliance is to be installed above ﬂoor level, a

solid, continuous platform must be constructed below the

appliance.

• Consider the height of hearth ﬁnish material (stone, brick,

et cetera) when building a ﬁreplace platform. The bottom of

the ﬁreplace must be level with ﬁnished hearth to allow for a

proper ﬁt of the safety barriers.

• Build the hearth to desired size and height. If a hearth

extension is desired, combustible material may be used.

3.6 Recess Construction

WARNING: All clearances to venting must be maintained.

Mounting a television above a ﬁreplace has become a common

practice. Television surface temperatures are aﬀected by mantel

depth, ceiling heights, and wall and mantel construction material.

Most television manufacturers specify in their instructions that a

television should not be installed on, near, or above a heat source.

Television location rests solely on the homeowner. It is the

homeowner’s responsibility that the preferred TV mounting and

mantel design will not exceed the listed maximum operation

temperature of their electronic goods.

Tests performed determined that surface temperatures did

not exceed 150°F (66°C) when a 4¼ in (108mm) deep recess

is constructed above the ﬁreplace. See illustrations below.
